A super-duper megavalue reader writes in re: this. His VoIP-centric take:
"If IBM, et al, lose this one, there could be potential licensing issues on a lot of VoIP-related software (especially software like Asterisk @ Home, which actually bundles the Linux OS with Asterisk on one CD). It would also increase the costs of the voice ISPs, as they'd start having to pay license fees (calculated at the moment on a completely unknown basis). Also, in light of all the 'open' stuff you've been talking about recently, I think this is quite interesting. Five big gun commercial giants getting together to keep something free for the good of the public. That's a sea change isn't it?"
